supply pack whereby superposed sets of the printed forms are maintained in general regis-' try for advance to the-printing point of the machine.

Another object of the invention is the provision of a simple, practical and efiicient construction of manifold record supply pack whereby superposed sets of printed forms with their carbons are maintained in general superposed registry with each other, but may have a limited longitudinal shift relative to each other for alignment or realignment, in case such shift be needed.

Another object of the invention is the provision of a simple and practical means connecting superposed strips or webs of a manifolding record supply pack of the character referred to, and adapted to restrain departure of the printed forms from predetermined. superposed registry, or aligned relation to each other, and which lends itself to. ready manufacture and t the various operations of the machine in which the record supply is used.

Other objects of the invention will in part be obvious and will in part appear hereinafter.

The invention accordingly comprises the features of construction, combinations of elements,

- Fig. 1, with the strips greatly separated from and arrangement of parts, which will be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated in the claims. v For a fuller understanding of the nature and objects of the invention reference should be had to the following detailed description taken in connection with the accompanying drawing, in which:

Fig. 1 is a perspective view illustrating an em bodiment of the invention;

Fig. 2 is an enlarged longitudinal section taken centrally of Fig. l substantially normal to the plane of the sheets;

Fig. 4 is a view illustrating a section of a transfer traveler web which may be employed;

Fig. 5 is a view illustrating a section of a modified form of transfer traveler web,.which may be used alone or conjointly with the transfer web of Fig. 4;

Fig. 6 is an enlarged view of one form of aligner, or web connector, which may be used;

Figs. 7 and 8 illustrate further modified forms of aligner; and

Fig. 9 is a diagrammatic view illustrating the aligner in position in webs which have been shifted relative to each other.

Referring now more specifically to the draw ing, the manifolding record supplypack is indicated in zigzag folded condition at I. The zigzagfolds provide a convenient assemblage from which the work web may be drawn or advanced to the typewriter, the billing machine, or the like. It is to be understood, however, that instead of the zigzag folding, the work web might be in rolled form. The work web includes a series of traveler webs, or traveler strips, in superposed relation to each other so as to form a pack or a composite work web.

Referring to Fig. 3, the numerals 2, 3, l, and 5 indicate foremost sections of four record traveler webs. Interleaved with these record webs are the transfer traveler webs B, l, and 8. The transfer traveler webs are adapted to transfer inscription, typewritten or autographic, from the original record web 2 to the underlying record webs 3, i, and 5, and may be made of the usual carbon paper of commerce, such for instance as I the carbons employed for duplicating copies in ordinary typewriting. As illustrated, however, the transfer webs 6, l, and 8 are carbon coated on their under faces only. The record traveler webs may be made of different colors, the shade lines on the webs 3, l, and 5 denoting such fact. When the work'web thus described is in operative position for receiving inscription, the several webs or strips will be close together as indicated in Fig. 1, the uppermost web or strip 2 being the original, the copy being received upon each of the underlying webs, some of which'webs will, of course, be intermediate the undermost web 5 and the original, web 2. a

The original web 2 will be provided with a series of printed forms, as for instance bill forms, respective of these forms being indicated by the numeral 9. They occur in longitudinal series on the original web, and the underlying webs are provided with similar printed forms so that when in superposed registry with the original forms,

. printed forms.

inscription made on the latter will be duplicated in the same relative position on the underlying When the work web composed of the individual traveler webs and transfer webs is drawn or fed to position in the machine, it will be seen that there is ample opportunity for unrestrained webs to shift longitudinally and laterally relative to each other so that an advance set of superposed forms may shift out of superposed registry relation to each other. One of the objects of the present invention is to restrain such relative shift and on the other hand, when a minimum amount of shift is needed for aligning or registering the forms, to limit the amount of such relative shift.

In the work web is a longitudinal series of stripcontrolling apertures, the apertures in the traveler web 2 being indicated by the numeral [0. Each of the underlying traveler webs or strips is provided with a similar series of apertures which is adapted to register or align in superposed relation with the series in the original strip.

The apertures occur at different points in the length of the work web, or pack. Carried by the work web are aperture-engaging and strip aligning members. In the embodiment illustrated, each of these members is indicated by the numeral I I. It passes through the apertures in the several strips, and consequently threads through the apertures in the work web. The member II has parts or arms l2 and I3, each of which lies outside the work web, one arm l2 facing the original or upper record traveler web 2 and the other arm [3 facing the lower record traveler web 5, the arms 12 and I3 being fast or secured to the respective traveler webs 2 and 5. In the embodiment illustrated, the aligner members H and the arms [2 and [3 thereof are formed of an integral sheet of relatively soft, flexible material, such as paper, which latter may be of the approximate weight of that of the record strips employed. The member II and the arms l2 and I3 may. be produced by folding an integral sheet of paper, and it will be seen that the arms [2 and i3 lap onto the upper and lower strips of the work web. Thereupon, the arms l2 and I3 are secured to said upper and lower strips respectively as by being pasted to the latter.

By the above described construction it will be seen that as the advance set of forms is gripped and drawn forward, the work web advances from its supply, as the zigzag folds hereinbefore explained, or the roll supply (not illustrated), and each set of superposed forms will be restrained by the aligners II from shifting relative to each other, so that superposed registry of printed forms will be substantially maintained for any set arriving at inscribing position. It is to be noted, however, that although the arms l2 and I3 of the strip aligners are firmly secured to the upper and lower traveler strips, nevertheless the member H which threads through the traveler strips may bend or fold relative to the respective arms 12 or l3, and thereby permit shift of the traveler strips relative to each other to a controlled degree, as for instance illustrated in Fig. 9, wherein the member II has, so to speak, pivoted, as on a hinge, around an edge of the arm i3 of the aligner, and has assumed a position at quite a different angle to the arms 12 and it than it has in Fig. 3, which latter illustrates the initial position of the strips before the relative shift therebetween.

It will be seen that the apertures ll partly transversely divide each of the traveler strips at points between each two successive sets of printed forms, so as to facilitate tearing the printed forms apart on transverse lines. In addition to the apertures l0, however, each traveler strip is provided with transverse dividing weakening lines l4 leading to the respective apertures l and to the points of passage of the strip aligners through the traveler strips. By providing the series of transverse weakening lines H, the superposed, advance sets of registering printed forms may-be parted from succeeding sets along lines which intersect the apertures l0, althoughit is to be understood that the apertures It! may be close to the weakening lines H instead of being in transverse direct alignment therewith, without departing from the invention. In other words, the apertures Ill through which the strip-aligners or securing devices pass, as well as the securing devices themselves, may be contiguous or in juxtaposition to the respective weakened lines H. The lines I! provide weakened severance lines for severing the strips.

In the present embodiment each of the arms of the paper strip aligners lies on the surface of an outer web, and each arm extends from the adjacent aperture of the work web in a direction opposite to the normal direction of advance or feed of the work web through the inscribing machine. In this wise the arms are of little, if any, obstruction to the passage of the work web through the machine. Also in the present embodiment, the strip aligning members thread loosely through the apertures in the strips intermediate the upper and lower strips of the work web, so that the intermediate strips are, as it were, strung on the aligners and are adapted for slight movements on the aligners as the occasion of use may demand. This imparts an added flexibility of relative movement to the strips of the work web. Nevertheless, it is to be understood that such relative movement is provided for by the flexibility of the strip aligner and on account of the different angles which the medial portion H of the strip aligner may assume relative to'the arms l2 and i3, which latter are fixed to the webs.

In the embodiment illustrated in Figs. 1 and 3, the strip connectors or aligners are substantially U-shaped members, in which the arms I2 and I3 directly overlie each other on the workweb. The U-shaped members may be angular as in Fig. 6, or curved as in Fig. 8. Further, it is to be understood that instead of having the arms l2 and I3 immediately above each other, as in Figs. 3 and 6, one arm may extend in one direction and the other in the opposite direction, as indicated in Fig. '7, wherein the upper and lower arms are respectively indicated by the numerals l5 and I6. When using aligners. .of the type illustrated in Fig. 7, and in which transverse weakening lines lead up to the relevant apertures in the strips, one or another, or both, or the arms l5 and I6 may be weakened, as indicated by the dotted lines i1 and I8, so

as readily to be parted during the tearing opersheets will be more or less removably held in place against other than deliberate separation from the parted set.

, notches or openings in its edge, these notches being generally indicated by the numerals i8, whereas vthe'transfer strips 6, l, and 8 intercept these notches til at one side of the work web. At the opposite side of the work web the transfer strips are provided with a series of notches i9 which are intercepted by the-record strips.

. In other words, marginal portions of the transwhereas the record sheets may be grasped adfer strips are aligned with the notches it depthwise of the assembly at one part of each set of leaves or forms, while marginal portions of the record strips or webs aresimilarly aligned with the notches W at another or spaced point of each said set. It will be noted also that the grip-forming apertures or notches i8 and i9 are positioned only in the vicinity of alternate weakening division lines it in the respective record and transfer strips, preferably extending to points both forwardly and rearwardly of the respective division lines and symmetrically arranged with reference thereto. The apertures in each of the strips are thus longitudinally spaced apart distances equal to the combined length of the two form leaves or sheets. The grip forming apertures l8 and I9 are arranged in sets depthwise of the work web or record assembly and are respectively aligned with marginal portions of adjacent strips which thus form selective grip areas. The apertures id of the transfer strips are preferably longitudinally offset in the assembly one leaf length from the record strip apertures it so that the selective grip formations provided by these apertures are positioned at diagonally opposite corners of each of the leaf sets. The weakened severance or'division lines it are, as shown, preferably arranged one above another in groups positioned at form length intervals along the assembly thus facilitating severance of the leaf sets along the respective groups. When an advance set of forms is parted from the work web, all the superposed transfer sheets thereof may be grasped through the notches it without grasping the record sheets,

jacent the notches it without grasping the transfer sheets. Consequently, a slight pull in opposite direction will immediately separate all the transfer sheets from the inscribed record sheets.

It will be observed that in the embodiment disclosed all the traveler webs or strips are flexibIy cQnnected together in a manner to permit longitudinal shift of individual webs relative to fastening and aligning members It is preferably of a width to substantially bridge the correspending aperture ill. The members i! will thus contact at their lateral edges with the corresponding strips atthe ends of said apertures,

thus holding both the record and transfer strips at all times in lateral alignment with each other.

An important feature of the invention is the association of the transfer material with the record traveler webs in a work-web of which the piles are controlled by the aligners, as already explained. In the embodiment illustrated, each record traveler web and each transfer traveler web is a continuous paper strip, one being coated or embodying the transfer material, as carbon transfer material. It is to be understood, however, that, instead of using a continuous, transfer traveler web, individual and distinct from the record web, the record web may be carbon coated on its under face, or may have a longitudinal series of short strips or sheets oftransfer paper attached as by spots of paste to the under face of the much longer record traveler web, without departing from certain aspects of the invention.

Since certain changes may be made in the above construction and difi'erent embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or ,shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.
